Yarmouk Martyrs Brigade

The Yarmouk Martyrs Brigade was a Sunni Muslim rebel group in southern Syria formed in August 2012 during the Syrian Civil War. The group used to be affiliated with the Syrian Opposition FSA Southern Front and was cooperative with the Free Syrian Army, but it later became isolated and joined the Islamic State of Iraq and Syria. In early March 2013, the group kidnapped 21 United Nations peacekeepers from the Philippines, giving them infamy; the group not only fought against the opposition's Syrian Arab Army enemies, but also against fellow Islamist groups such as the al-Nusra Front, Syria Revolutionaries Front, and Islamic Muthanna Movement.
